Main API: sudokuJs(options: SudokuJS)

Generate a fresh Sudoku puzzle. Options include:

• level: The desired difficulty (0-4, with 4 being the most challenging).
• emptyHoleCount: Directly set the number of empty cells. (Takes precedence over level if both are provided.)
• strict: Enforce a unique solution for the generated puzzle. Default is true.

Utility Functions

• generate(digHoleCount: number): Synchronously produce a puzzle with a set number of empty cells.
• generateAsync(digHoleCount: number): Async version of the above.
• generateByLevel(level: number): Craft a puzzle of a particular difficulty level.
• solve(board: BoardTypes, args: { strict?, emptyHoleChar, as? }): BoardTypes: Resolve any Sudoku board.

Class: Sudoku

An object-oriented interface to engage with Sudoku boards.

Methods:

• getBoard(as: AsTypes): Retrieve the current board state.
• getAnswer(as: AsTypes): Obtain the board's solution.
• validate(): Check if the current board state is valid.
• debug(): Gain insights into the board's internal state and potential solutions.
